WATER Specification 0 Application filed May 5,

and. State.- of California, have invented cer-,

tain new andiusefullmprovements in Water Heaters and I do hereby'declare the following to. beafull, clear, and exact description of the invention, such as will enable others skilled in theartato which ituappertains tomake. and use the same.

This invention relates to water heaters and more particularly to that type used for household and similar purposes.

An object of: the invention is to provide aneasily assembled'and easily'cleaned water heater. consisting of. comparatively few parts.

Another. object of the invention is to construct a. water heater havinga novel water circulating pathor route through whichthe water is passed for intensely heating the Same. i g V Another. object of the inve-ntion" is toproduce acwa'tenheating unit, the several parts ofwhich canibe economically. manufactured, and subsequently assembled in a minimum amount. of timeby. unskilled. labor.

jlVTth; these. and other objects in view the inventionfifurther consists in the arrangement and construction of the several parts hereinafter described andv pointed out in the appended. claims. 1

1 and:2respectively,so as to form a series of intercommunicating chambersproducing a novel path oftravel for the water.

Theheaders 1 and 2 are provided with a series of projecting fins or ribs-6 the outer edgesof which are preferably machined so that the innerfaces of the front and b ack plates tand 5 when abuttedlagainst theribs asshown, serve to form water-tight jointsat all points throughout the water circulating chambers The inner faces of the plates 4 and 5 may also bemachined or ground as will be understood. c

Thearrangement of' the projecting ribs 6 isnovel in that they extend vertically and,

horizontally thereby dividing the heater into adj acent series .of intercommunicating chambers forming predetermined water circulating: paths or routes at the front and baclcof the heater. Referring particularly to F ig-- ures 1, 2 and 3, a water inlet chamber 7 is shown as communicating with some of the tubes 3, through whichlatter the waterflows to the rear of the heater intoone of a series of chambers 8 arranged upon-'oneside ofthe back of theheater. From this chamber 8 the water'fiows through other communicating; tubes 3 into one of a series of chambers Qprovided between the ribs 6 at the front of the heater and upon one side thereof as shown. Thewater flows from'the chamber 9 into communicating tubes 3-and discharges, into another-one, of thechambers 8 at the rearof theheateryand from this said: chamber 8 it continues to pass again to=the front of the heater into-another one of the chambers 9, and so on untilit reaches the top of the heater and empties into a relatively Wide chamber 10. The chamber 10 extends across the top of the heater and has communicating therewith some of the tubes 3whichserve to convey the water rearwardly into one of a series of chambers 11 arranged at the rear of the heater adjacent. the chambers 8 hereinbefore referred to. From the chamberll the water passes forwardly through the cominunicating tubes 3 into one of a series of chambers 12 arranged at the front of the heater adjacent the chambers .9 hereinbefore described. v

y The water continues to flow downwardly through the tubes 3 and intercommunicating chambers 11 and 12 until it reaches the bottom of the heater, where it empties into a relatively wide chamber 13. extends across the bottom of the heater and This chamber 13.

has communicating therewith tubes 8 which serve to convey the water rearwardly into one of a series of chambers 14 arranged at the rear of the heater adjacent the chambers 11, and beneath the chambers 8, above referred to. The water now flows from the chamber 1 1 forwardly again through the tubes 8 into one of a series of communicating chambers 15 at the front of the heater, adjacent the said chambers 12 and beneath the chambers 9 hereinbefore described. The water continues to flow upwardly through the aforesaid intercommunicating chambers, until it discharges into the outlet chamber 16 arranged at the front of the heater and in close proximity to the inlet chamber 7.

From the foregoing it will be seen that a relatively tortuous path of travel or route of the water is obtained from a comparatively simple construction and that the water is gradually heated to a maximum intensity from the time it is introduced into the heater.

An inlet pipe 17 and an outlet pipe 18 are connected to the chambers 7 and 16 respectively.

The relative closeness of location of these connections has been found to be useful in reducing the time that it takes to assemble and connect up the heater, as will be understood.

The heater is provided with a hinged door.

19 attached to one side of the heater upon hinges 20. The purpose of the door is to facilitate cleaning the heater and to provide means for readily inspecting the same.

A plate 21 forms the opposite side wall of the heater and is detachably secured to the headers 1 and 2 by means of bolts, cap screws or similar fastening devices.

A burner 22 is shown at thebottom of the heater for supplying the necessary heat which passes upwardly through the heater contacting with the several tubes and the interior walls.

The heater is provided with a cap or top section 23 of dome or similar shape as shown.

The headers 1 and 2 are preferably designed to extend to the bottom of the heater, as shown, andthe hinged door 19 and side plate 21 are likewise extended, thereby producing a completely enclosed structure the better to conserve heat.

The fastening devices for the several parts may be bolts or cap screws of standard construction, although it will be understood that various other devices may be employed.

Various changes in the proportion and arrangement of the several parts may be made and I do not limit myself to the exact construction herein set forth.

I claim 1. A water heater comprising oppositely arranged headers having a plurality of relatively short projecting ribs upon the outer faces thereof arranged so as to form two sets of headers on each side of the heater, a plate fitted against the ribs of the headers, said plate forming one wall of a series of relatively small water circulating chambers at the front and back of the heater, tubes connecting the corresponding sets of headers for establishing communication with the aforesaid chambers, a water inlet provided at the front midway of the heater and communicating with one of the circulating chambers, and an outlet for the heated water, said outlet communicating with another of said circulating chambers and arranged midway of the heater in close proximity to the aforesaid inlet.

2. Awater heater comprising oppositely disposed headers, a plurality of relatively short projecting ribs upon the outer faces thereof, said ribs being arranged in vertical and horizontal relation to each other so as to form two vertical sets of headers on each side of the heater, a plate fitted against the headers, said plate being adapted to abut against the said projecting ribs and to form therewith a series of relatively small chambers upon acent sides of the heater at the front and back thereof, tubes connecting the corresponding sets of headers and establishingcommunication with the aforesaid chambers for conveying the water upwardly upon one side of the heater and downwardly upon the adjacent side thereof, an inlet for the water to be heated, and an outlet for the heated water.

3. A water heater comprising oppositely disposed headers having a plurality of relatively short projecting ribs upon the outer faces therof, said ribs being arranged in vertical and horizontal relation to each other and provided with machined edges, a plate fitted against the said edges of the ribs of each header for completing a series of relatively small chambers upon adjacent sides of said vertical ribs at the front and back thereof, relatively wide and shallow chambers at the top and bottom of said heater, and communicating with the aforesaid relatively small chambers, tubes secured to said headers and communicating with the aforesaid chambers, an inlet communicating with one of the chambers aforesaid midway of the heater and upon one side thereof, and an outlet arranged in close proximity to the said inlet,whereby the water is conveyed from the inlet aforesaid upwardly upon one side of the heater, thence downwardly upon the adjacent side of the heater and returned upwardly upon the first mentioned side of the heater to the outlet aforesaid.

a. A water heater comprising oppositely disposed headers having a plurality of relatively short ribs, projecting from the outer faces thereof, said ribs forming adjacent series of relatively shallow chambers upon with the chambers, an inlet for the Water to 10 be heated, and an outlet for the heated water.

In testimony whereof I afiix my signature, in presence of two subscribing Witnesses.
